The permeability of textile reinforcements is a crucial input for the simulation of the impregnation stage of a composite material fabrication process. In this paper
we present a fast and accurate simulation method for the permeability of a textile
reinforcement, based on a finite difference discretisation of the Stokes equations.
Results for single layer, multi layer and sheared models are discussed. The influence
of intra-yarn flow and periodic or wall boundary conditions are considered. We
compare the numerically computed permeability values with experimental data.
